MAB/GIN SCALE FOR TYPEWRITING HACHINES.

Specification of Letters Patent.

Patented May 30, 1922.

Original application filed January 13, 1921, Serial No. 438,924. Divided and this application filed May To all whom it may concern:

Be it known that we. EDWARD BERNARD and Lewis CARY hirnns, both citizens of the United States, residing in Brooklyn, in the county of Kings, city and State of New York. have invented certain new and useful Improvements in MaI'gin Scales for TypeWrit-ing Machines, of which the following is a specification.

In our application for patent filed Jan. 13, 1921, No. 436,924, we have shown all of the mechanism of a typewriting machine embodying various improvements made by us. The present application for patent is a division of said application filed Jan. l3, 1921. and the claims herein are confined to certain scales employed in the machine.

The paper table is formed on one side with a depression in which is mopntednt'sicale plate which is adjustable crosswise of the table. The guide for the margin of the paper is adjustable transversely of the table and may be set at any desired position, which position will be indicated on the scale of the paper table and on the scale of the margin stop rail. In this way, means is provided whereby the margin may be quickly adjusted by devices in plain view and within easy reach of the operator in a. machine in which the margin stops and their supportin rail are mounted in rear of the platen and in rear of the paper table.

In the accompanying drawings 1- Figure l is a view on enlarged scale showing a portion of the platen, the paper table with our improvements applied, and part of the line-space mechanism.

Figure 2 shows a portion of the paper table with our improved adjustable scale thereon and it also shows how the guide for the margin of the paper is supported. The margin stop rail and one of the margin stops is indicated by dotted lines.

Figure 3 is a detail view. in section, showing particularly how the margin scale is mounted and adjusted on the table.

,The drawings show a portion of a paper table Q carrying an adjustable scale plate.

R, provided with proper graduations as indicated. The place is located in a depression q in the table and carries studs 2' extending through slots r in the table and carrying nuts r In this way the scale plate is located below the plane of the table and forms no Serial No. 473,162.

obstruction .to the paper, and means is also provided for giving the plate a delicate ad; justmentto conform to other scales on the machine. It has heretofore been proposed to provide a margin scale on the paper table but the custom heretofore has been to print the scale on the table by a transfer process. It has been found that such a scale becomes blurred, scratched or otherwise married and IS not suliiciently accu'rate. These objections have been overcome by our improvements.

In front-strike visible typewriting machines where the carriage structure and its tracks or uide rails and the margin stops are locatecT behind the line. of print and be hind the paper table, the stops are not so readily accessible. for frequent adjustments asthey arein some machines where the stops are Located in front of the line of print, although such machines have objectionable features not present in machines Where the margin stops and their rail are removed from the front of the machine so as to leave a clear space in front of the line of print. Wediave provided means whereby the margin may be quickl adjusted by devices in plain view andwit in easy reach of the operator in a machine in which the usual margin stops and their supportin rail are mounted inrrear of the platen ant the paper table so that all of theadvantages of a machine of this type are preserved, while the facility with which the margin of the paper may be adjusted is greatly enhanced, making it possible to :l(i]U.St the margin of this type of machine as easily as in machines where the margin stops are arranged in the front part of the machine.

In setting the margin stops it is customary to place the left-hand stop at zero position on the margin scale so that upon each return of the carriage it rests at that point.

According to our invention the stop is placed at a predetermined position on the indicating scale other than the normal zero position. This position normally brings the carriage, on its return, to a predetermined position which leaves a margin at the lefthand side of the paper equal to the distance between the margin stop position and the left-hand edge of the paper.

ln' order, to adjust the margin within these limits, when it is desired to vary the margin as the printing progressps, we effect the control by an adjustable paper gauge on the table, the position of which gauge ma bev easily changed and it co-operates with the scale on the table.

The table is provided with a tubular extension T Which -serves as a hearing or support for a rod T which is adjustable end wise in the hearing. The rod carries a paper guide L which overlies the left-hand portion of the table below or in front of the scale R. The guide Y may be adjusted tl'zllbversely over the table along the scale and held in the desired or selected position. The relation of the scale R and the guide I; to the graduated margin stop rail 1) and the adjustable stop E, is indicated in Fig. i.

Assuming the margin stop to he in a PM" determined position. say at 1:) on the scale. and the paper gauge or guide I is at its extreme left-hand limit on the table. a desired margin may he obtained hr moving the guide to the right on the tahle until it rointides. for instance. with the Figure 3 0n the scale R. The margin is thus reduced live spaces and it the guide he mored to 10. or some other position on the si-ale. the margin becomes to] re.- mndin; rl\- redured. It will. therefore. he seen that by means of the margin stop (loeated at a predetermined position) paper tahle. srale and paper guide ('arried h the table. the margin control of the printim. point is etler-ted Irv the adjustments of the paper relatively to the paper guide in t' lntl'tl listllltiltlll to the usual prartire of inserting the paper and allowing the margin stop in its normal zero position to control the loration of the paper. It will also he ohserved that our invention contemplates the adjustment of the paper guide on the table rather than adjustments of the margin stop for variable margins.
